| - Included support for OPL3-SA1 and SoftOSS |
| |
| Since 3.8 |
| - Fixed SNDCTL_DSP_GETOSPACE |
| - Compatibility fixes for Linux 2.1.47 |
| |
| Since 3.8-beta21 |
| - Fixed all known bugs (I think). |
| |
| Since 3.8-beta8 |
| - Lot of fixes to audio playback code in dmabuf.c |
| |
| Since 3.8-beta6 |
| - Fixed the famous Quake delay bug. |
| |
| Since 3.8-beta5 |
| - Fixed many bugs in audio playback. |
| |
| Since 3.8-beta4 |
| - Just minor changes. |
| |
| Since 3.8-beta1 |
| - Major rewrite of audio playback handling. |
| - Added AWE32 support by Takashi Iwai (in ./lowlevel/). |
| |
| Since 3.7-beta# |
| - Passing of ioctl() parameters between soundcard.c and other modules has been |
| changed so that arg always points to kernel space. |
| - Some bugfixes. |
| |
| Since 3.7-beta5 |
| - Disabled MIDI input with GUS PnP (Interwave). There seems to be constant |
| stream of received 0x00 bytes when the MIDI receiver is enabled. |
| |
| Since 3.5 |
| - Changes almost everywhere. |
| - Support for OPTi 82C924-based sound cards. |
| |
| Since 3.5.4-beta8 |
| - Fixed a bug in handling of non-fragment sized writes in 16 bit/stereo mode |
| with GUS. |
| - Limited minimum fragment size with some audio devices (GUS=512 and |
| SB=32). These devices require more time to "recover" from processing |
| of each fragment. |
| |
| Since 3.5.4-beta6/7 |
| - There seems to be problems in the OPTi 82C930 so cards based on this |
| chip don't necessarily work yet. There are problems in detecting the |
| MIDI interface. Also mixer volumes may be seriously wrong on some systems. |
| You can safely use this driver version with C930 if it looks to work. |
| However please don't complain if you have problems with it. C930 support |
| should be fixed in future releases. |
| - Got initialization of GUS PnP to work. With this version GUS PnP should |
| work in GUS compatible mode after initialization using isapnptools. |
| - Fixed a bug in handling of full duplex cards in write only mode. This has |
| been causing "audio device opening" errors with RealAudio player. |
| |
| Since 3.5.4.beta5 |
| - Changes to OPTi 82C930 driver. |
| - Major changes to the Soundscape driver. The driver requires now just one |
| DMA channel. The extra audio/dsp device (the "Not functional" one) used |
| for code download in the earlier versions has been eliminated. There is now |
| just one /dev/dsp# device which is used both for code download and audio. |
| |
| Since 3.5.4.beta4 |
| - Minor changes. |
| |
| Since 3.5.4-beta2 |
| - Fixed silent playback with ESS 688/1688. |
| - Got SB16 to work without the 16 bit DMA channel (only the 8 bit one |
| is required for 8 and 16 bit modes). |
| - Added the "lowlevel" subdirectory for additional low level drivers that |
| are not part of USS core. See lowlevel/README for more info. |
| - Included support for ACI mixer (by Markus Kuhn). ACI is a mixer used in |
| miroPCM sound cards. See lowlevel/aci.readme for more info. |
| - Support for Aztech Washington chipset (AZT2316 ASIC). |
| |
| Since 3.5.4-beta1 |
| - Reduced clicking with AD1848. |
| - Support for OPTi 82C930. Only half duplex at this time. 16 bit playback |
| is sometimes just white noise (occurs randomly). |
| |
| Since 3.5.2 |
| - Major changes to the SB/Jazz16/ESS driver (most parts rewritten). |
| The most noticeable new feature is support for multiple SB cards at the same |
| time. |
| - Renamed sb16_midi.c to uart401.c. Also modified it to work also with |
| other MPU401 UART compatible cards than SB16/ESS/Jazz. |
| - Some changes which reduce clicking in audio playback. |
| - Copying policy is now GPL. |
| |
| Since 3.5.1 |
| - TB Maui initialization support |
| Since 3.5 |
| - Improved handling of playback underrun situations. |
| |
| Since 3.5-beta10 |
| - Bug fixing |
| |
| Since 3.5-beta9 |
| - Fixed for compatibility with Linux 1.3.70 and later. |
| - Changed boot time passing of 16 bit DMA channel number to SB driver. |
| |
| Since 3.5-beta8 |
| - Minor changes |
| |
| Since 3.5-beta7 |
| - enhancements to configure program (by Jeff Tranter): |
| - prompts are in same format as 1.3.x Linux kernel config program |
| - on-line help for each question |
| - fixed some compile warnings detected by gcc/g++ -Wall |
| - minor grammatical changes to prompts |
| |
| Since 3.5-beta6 |
| - Fixed bugs in mmap() support. |
| - Minor changes to Maui driver. |
| |
| Since 3.5-beta5 |
| - Fixed crash after recording with ESS688. It's generally a good |
| idea to stop inbound DMA transfers before freeing the memory |
| buffer. |
| - Fixed handling of AD1845 codec (for example Shuttle Sound System). |
| - Few other fixes. |
| |
| Since 3.5-beta4 |
| - Fixed bug in handling of uninitialized instruments with GUS. |
| |
| Since 3.5-beta3 |
| - Few changes which decrease popping at end/beginning of audio playback. |
| |
| Since 3.5-beta2 |
| - Removed MAD16+CS4231 hack made in previous version since it didn't |
| help. |
| - Fixed the above bug in proper way and in proper place. Many thanks |
| to James Hightower. |
| |
| Since 3.5-beta1 |
| - Bug fixes. |
| - Full duplex audio with MAD16+CS4231 may work now. The driver configures |
| SB DMA of MAD16 so that it doesn't conflict with codec's DMA channels. |
| The side effect is that all 8 bit DMA channels (0,1,3) are populated in |
| duplex mode. |
| |
| Since 3.5-alpha9 |
| - Bug fixes (mostly in Jazz16 and ESS1688/688 supports). |
| - Temporarily disabled recording with ESS1688/688 since it causes crash. |
| - Changed audio buffer partitioning algorithm so that it selects |
| smaller fragment size than earlier. This improves real time capabilities |
| of the driver and makes recording to disk to work better. Unfortunately |
| this change breaks some programs which assume that fragments cannot be |
| shorter than 4096 bytes. |
| |
| Since 3.5-alpha8 |
| - Bug fixes |
| |
| Since 3.5-alpha7 |
| - Linux kernel compatible configuration (_EXPERIMENTAL_). Enable |
| using command "cd /linux/drivers/sound;make script" and then |
| just run kernel's make config normally. |
| - Minor fixes to the SB support. Hopefully the driver works with |
| all SB models now. |
| - Added support for ESS ES1688 "AudioDrive" based cards. |
| |
| Since 3.5-alpha6 |
| - SB Pro and SB16 supports are no longer separately selectable options. |
| Enabling SB enables them too. |
| - Changed all #ifndef EXCLUDE_xx stuff to #ifdef CONFIG_xx. Modified |
| configure to handle this. |
| - Removed initialization messages from the |
| modularized version. They can be enabled by using init_trace=1 in |
| the insmod command line (insmod sound init_trace=1). |
| - More AIX stuff. |
| - Added support for synchronizing dsp/audio devices with /dev/sequencer. |
| - mmap() support for dsp/audio devices. |
| |
| Since 3.5-alpha5 |
| - AIX port. |
| - Changed some xxx_PATCH macros in soundcard.h to work with |
| big endian machines. |
| |
| Since 3.5-alpha4 |
| - Removed the 'setfx' stuff from the version distributed with kernel |
| sources. Running 'setfx' is required again. |
| |
| Since 3.5-alpha3 |
| - Moved stuff from the 'setfx' program to the AudioTrix Pro driver. |
| |
| Since 3.5-alpha2 |
| - Modifications to makefile and configure.c. Unnecessary sources |
| are no longer compiled. Newly created local.h is also copied to |
| /etc/soundconf. "make oldconfig" reads /etc/soundconf and produces |
| new local.h which is compatible with current version of the driver. |
| - Some fixes to the SB16 support. |
| - Fixed random protection fault in gus_wave.c |
| |
| Since 3.5-alpha1 |
| - Modified to work with Linux-1.3.33 and later |
| - Some minor changes |
| |
| Since 3.0.2 |
| - Support for CS4232 based PnP cards (AcerMagic S23 etc). |
| - Full duplex support for some CS4231, CS4232 and AD1845 based cards |
| (GUS MAX, AudioTrix Pro, AcerMagic S23 and many MAD16/Mozart cards |
| having a codec mentioned above). |
| - Almost fully rewritten loadable modules support. |
| - Fixed some bugs. |
| - Huge amount of testing (more testing is still required). |
| - mmap() support (works with some cards). Requires much more testing. |
| - Sample/patch/program loading for TB Maui/Tropez. No initialization |
| since TB doesn't allow me to release that code. |
| - Using CS4231 compatible codecs as timer for /dev/music. |
| |
| Since 3.0.1 |
| - Added allocation of I/O ports, DMA channels and interrupts |
| to the initialization code. This may break modules support since |
| the driver may not free some resources on unload. Should be fixed soon. |
| |
| Since 3.0 |
| - Some important bug fixes. |
| - select() for /dev/dsp and /dev/audio (Linux only). |
| (To use select() with read, you have to call read() to start |
| the recording. Calling write() kills recording immediately so |
| use select() carefully when you are writing a half duplex app. |
| Full duplex mode is not implemented yet.) Select works also with |
| /dev/sequencer and /dev/music. Maybe with /dev/midi## too. |
| |
| Since 3.0-beta2 |
| - Minor fixes. |
| - Added Readme.cards |
| |
| Since 3.0-beta1 |
| - Minor fixes to the modules support. |
| - Eliminated call to sb_free_irq() in ad1848.c |
| - Rewritten MAD16&Mozart support (not tested with MAD16 Pro). |
| - Fix to DMA initialization of PSS cards. |
| - Some fixes to ad1848/cs42xx mixer support (GUS MAX, MSS, etc.) |
| - Fixed some bugs in the PSS driver which caused I/O errors with |
| the MSS mode (/dev/dsp). |
| |
| Since 3.0-950506 |
| - Recording with GUS MAX fixed. It works when the driver is configured |
| to use two DMA channels with GUS MAX (16 bit ones recommended). |
| |
| Since 3.0-94xxxx |
| - Too many changes |
| |
| Since 3.0-940818 |
| - Fixes for Linux 1.1.4x. |
| - Disables Disney Sound System with SG NX Pro 16 (less noise). |
| |
| Since 2.90-2 |
| - Fixes to soundcard.h |
| - Non blocking mode to /dev/sequencer |
| - Experimental detection code for Ensoniq Soundscape. |
| |
| Since 2.90 |
| - Minor and major bug fixes |
| |
| Since pre-3.0-940712 |
| - GUS MAX support |
| - Partially working MSS/WSS support (could work with some cards). |
| - Hardware u-Law and A-Law support with AD1848/CS4248 and CS4231 codecs |
| (GUS MAX, GUS16, WSS etc). Hardware ADPCM is possible with GUS16 and |
| GUS MAX, but it doesn't work yet. |
| Since pre-3.0-940426 |
| - AD1848/CS4248/CS4231 codec support (MSS, GUS MAX, Aztec, Orchid etc). |
| This codec chip is used in various sound cards. This version is developed |
| for the 16 bit daughtercard of GUS. It should work with other cards also |
| if the following requirements are met: |
| - The I/O, IRQ and DMA settings are jumper selectable or |
| the card is initialized by booting DOS before booting Linux (etc.). |
| - You add the IO, IRQ and DMA settings manually to the local.h. |
| (Just define GUS16_BASE, GUS16_IRQ and GUS16_DMA). Note that |
| the base address bust be the base address of the codec chip not the |
| card itself. For the GUS16 these are the same but most MSS compatible |
| cards have the codec located at card_base+4. |
| - Some minor changes |
| |
| Since 2.5 (******* MAJOR REWRITE ***********) |
| |
| This version is based on v2.3. I have tried to maintain two versions |
| together so that this one should have the same features than v2.5. |
| Something may still be missing. If you notice such things, please let me |
| know. |
| |
| The Readme.v30 contains more details. |
| |
| - /dev/midi## devices. |
| - /dev/sequencer2 |
| |
| Since 2.5-beta2 |
| - Some fine tuning to the GUS v3.7 mixer code. |
| - Fixed speed limits for the plain SB (1.0 to 2.0). |
| |
| Since 2.5-beta |
| - Fixed OPL-3 detection with SB. Caused problems with PAS16. |
| - GUS v3.7 mixer support. |
| |
| Since 2.4 |
| - Mixer support for Sound Galaxy NX Pro (define __SGNXPRO__ on your local.h). |
| - Fixed truncated sound on /dev/dsp when the device is closed. |
| - Linear volume mode for GUS |
| - Pitch bends larger than +/- 2 octaves. |
| - MIDI recording for SB and SB Pro. (Untested). |
| - Some other fixes. |
| - SB16 MIDI and DSP drivers only initialized if SB16 actually installed. |
| - Implemented better detection for OPL-3. This should be useful if you |
| have an old SB Pro (the non-OPL-3 one) or a SB 2.0 clone which has a OPL-3. |
| - SVR4.2 support by Ian Hartas. Initial ALPHA TEST version (untested). |
| |
| Since 2.3b |
| - Fixed bug which made it impossible to make long recordings to disk. |
| Recording was not restarted after a buffer overflow situation. |
| - Limited mixer support for GUS. |
| - Numerous improvements to the GUS driver by Andrew Robinson. Including |
| some click removal etc. |
| |
| Since 2.3 |
| - Fixed some minor bugs in the SB16 driver. |
| |
| Since 2.2b |
| - Full SB16 DSP support. 8/16 bit, mono/stereo |
| - The SCO and FreeBSD versions should be in sync now. There are some |
| problems with SB16 and GUS in the FreeBSD versions. |
| The DMA buffer allocation of the SCO version has been polished but |
| there could still be some problems. At least it hogs memory. |
| The DMA channel |
| configuration method used in the SCO/System is a hack. |
| - Support for the MPU emulation of the SB16. |
| - Some big arrays are now allocated boot time. This makes the BSS segment |
| smaller which makes it possible to use the full driver with |
| NetBSD. These arrays are not allocated if no suitable sound card is available. |
| - Fixed a bug in the compute_and_set_volume in gus_wave.c |
| - Fixed the too fast mono playback problem of SB Pro and PAS16. |
| |
| Since 2.2 |
| - Stereo recording for SB Pro. Somehow it was missing and nobody |
| had noticed it earlier. |
| - Minor polishing. |
| - Interpreting of boot time arguments (sound=) for Linux. |
| - Breakup of sb_dsp.c. Parts of the code has been moved to |
| sb_mixer.c and sb_midi.c |
| |
| Since 2.1 |
| - Preliminary support for SB16. |
| - The SB16 mixer is supported in its native mode. |
| - Digitized voice capability up to 44.1 kHz/8 bit/mono |
| (16 bit and stereo support coming in the next release). |
| - Fixed some bugs in the digitized voice driver for PAS16. |
| - Proper initialization of the SB emulation of latest PAS16 models. |
| |
| - Significantly improved /dev/dsp and /dev/audio support. |
| - Now supports half duplex mode. It's now possible to record and |
| playback without closing and reopening the device. |
| - It's possible to use smaller buffers than earlier. There is a new |
| ioctl(fd, SNDCTL_DSP_SUBDIVIDE, &n) where n should be 1, 2 or 4. |
| This call instructs the driver to use smaller buffers. The default |
| buffer size (0.5 to 1.0 seconds) is divided by n. Should be called |
| immediately after opening the device. |
| |
| Since 2.0 |
| Just cosmetic changes. |
